zara, I would be initially responsible for (attempting) to faithfully re-create SCPs of which there are pictures/dimensions available.
Thus, for the most part, biological SCPs are kind of out of my area of expertise in terms of modelling.
However, once this gets started up, anyone else with knowledge of 3D modelling can be free to submit their ideas, and I can translate them into G-code for the printer.

No, I got that. The problem is that many many of the items don't have picture, and only a VERY vague description. 95%+ of those with attached images are copyrighted by someone else (there are a few with original art).

Most of the things we have either look completely normal (until you die) or they're some Eldridge horror or other weird looking thing……

1) For those with pictures, look into the copyrights and such, and ask the original people where it is. Hopefully, most of these pictures are under some sort of CC license, so this part should be easy.

2) For those without pictures or with extremely vague descriptions, ask the author if they could sketch something in mind.

Note that these only apply to SCPs - other Foundation-related paraphernalia can be printed, such as the Foundation Symbol, badges, weapons or something of the sort.

#1 - They really really aren't. Really. But like I say, other then a few that are REALLY interesting (SCP-173 comes to mind) most are pretty boring. And the ones that ARE interesting? They're not Creative Commons. (I think the actual art piece of SCP-173 by Izumi Kato sold for something like $100K…)

Would you be selling the miniatures? Because if the answer is no, we should be fine.

However, 3D printers and the materials for it can be kind of expensive. (Unless you already bought one, then you understand. What kind did you get if you have?)

If you are planning on selling them, the problem is that most of the SCPs on this site who have a picture on the file don't actually belong to the original poster, so all of the designs would have to be completely original based off the SCP file description.

For the most part, the first SCPs I will work on are those that I can obtain permission from the original author.
CC licensing for these photos should be able to extend to physical objects - I am looking at the legalities to make sure I'm not stepping on anyone's IP toes.

SCP-243, for one, especially if we could add a swarm of "animated" objects (held up by clear plastic or fishing line, I dunno). SCP-1032, especially if it could be made functional. SCP-184. Things like that.

Making a static version of SCP-1032 would be fairly easy, actually. I think they sell those types of clocks at Ikea, and any decent hobby shop would sell clock hands. A working one whould be harder - without special tools it would be harder to do more then the normal moving hands.

SCP-184 shouldn't be much more difficult then practice for someone learning the tools.

Yaks, I will not be selling the miniatures, because the original SCPs of which they are based off have the license attached to them. Once the machine is set-up, I will ask permission from authors of various SCPs.

I am working on constructing a RepRap Mendel (Original). Yes, is expensive, as I've already shilled out at least $100 CAD.

As mentioned, these printed miniatures will NOT be sold.
However, once in a while, I can give away models of successfully printed SCP/Foundation-related objects.
